I agree FD seems to be easy and it tastes fine to me. I've done the grocery store thing and been on outfitter trips where fancier dinners were done. To me it's fun to do fancier meals with  larger groups than solo trips. I think the shared dinners are another way of getting a group to feel together. There's more hands to share tasks around camp. Another reason to use FD while soloing, you do it all yourself and FD leaves time for other things. I always have some FD meals stashed in the food barrel for those days when traveling took a bit more out of you than expected and you're tired.

I think the thing that I miss the most after a few days is something crunchy, or with some tooth, as they say. So I've been carrying apples. Bring a wedge of cabbage too for slaw with your fish dinner. Apple, cabbage, olive oil, lemon juice, and salt & pepper. My GF brings bagels chips for the same reason. Eat'm along with the FD or soup for some crunch.

FD or store stuff, rehydrated mush gets old after a few days.
